NO. 2189. NEW FOSSIL BEETLES FROM FLORISSANT— WICKHA.][. 467 



Type. — In the Museum of the University of Colorado, collected at 

 Florissant, in 1906, by Prof. Cockerell's party and bearing his num- 

 ber 184. It came from Station 14, a most productive locality. 



Described from one specimen. The most striking superficial char- 

 acter of the insect is its rough punctuation, which extends even to 

 the antennal joints. The peculiar structural feature is the spatulate 

 emarginate prosternal process, which has been hard to match on any 

 Coleoptera known to me. An approach to it is seen in the Javanese 

 Belionota scutellaris, where the process is very similarly broadened 

 apically, but, instead of being simply emarginate, the tip in that 

 species is divided into three teeth or lobes. In other respects the 

 fossil is not at all close to the species cited, being far less specialized 

 in antennal, coxal, and tarsal structure. 



Genus PODABRUS Westwood. 



PODABRUS CUPESOIDES, new species. 



Plate 37, fig. 4. 



Form narrow, elongate, parallel. Head distinctly narrowed behind. 

 Antemiac long and slender, reaching nearly to the elytral apices, the 

 joints very httle serrate. Pro thorax about as long as the head but con- 

 siderably broader, sides obscurely preserved but apparently romiding. 

 Elytra, conjomtly, a little less than two and one-half times as long as 

 broad, their apices romiding. Abdomen, as preserved, extendmg 

 well beyond the elytral tips but probably distended as indicated by 

 the broad transverse bands which show location of the sutures. 

 Length, to tip of abdomen, 8 mm. ; to tip of elytra, 7 mm. ; of elytron, 

 5.35 mm.; width, across broadest part of elytra, 2.30 mm.

The type of this species bears a notable resemblance to a small 

 Cupes, partly because of the way in which it is disj^layed upon the 

 stone. The small size and long antennae wiU separate it from any 

 other Florissant fossil Podahrus, into which genus it seems to go by 

 the posterior constriction of the head and the trmicate pro thoracic 

 apex. The sculpture is of the finely scabrous tyi^e common among 

 the recent species. With the type, I have associated mider the same 

 name a considerable number of examples belonging to various other 

 collections, especially those of the Museum of Comparative Zoology 

 and the University of Colorado. It is possible that more than one 

 species is concerned, but I can find no definite basis of separation. 

 The texture of these beetles is so soft that they do not, as a rule, show 

 up weU as fossils and characters used in discrimmation of recent 

 forms, such as those founded upon structures of claws and maxillary 

 palpi, are never visible upon the stones.
